Hi guys! Im building ground control in an Ubuntu 15.1 box with qgroundcontrol cloned from the repository and running make with Qt 5.4.2 (GCC 5.2.1 20151010, 64 bit).. Ran into this error and was hoping you could tell me what to add or uncomment.

I'm not sure why you're getting an error, but those macros should be defined in libs/mavlink/include/mavlink/v1.0/common.h. The error location is new code and I haven't tried building it on Linux yet. So you could try removing those macros and see if the build completes. Replace MAV_FRAME_GLOBAL_RELATIVE_ALT_INT with the number 6 and MAV_FRAME_GLOBAL_INT with the number 5. If you still get other errors relating to mavlink, then the problem is most likely elsewhere. Please let me know what you find.

Thanks Max- I hate to bring problems to your plate. I made those changes within UAS.cc and then built only to have it error onQGCMapWidget.cc where i tried to replace those variables with numbers too. It continued to build and now has errors here- EDITED

Cool! Actually I think I just found the base issue... Looks like I"m using a newer version of the Mavlink library for my own QGC builds. So the problem can also be fixed by updating the library included in the QGC repo, or changing the MAVLINKPATH variable in qgroundcontrol_aq.pro to point to a newer version (eg. MAVLINKPATH = e:/lib/mavlink/include ). This would actually apply to builds for any OS. Thanks for reporting!

Yea the festival/speech stuff is vague... I've gotten it to work several times but still not really sure how!
